Specification of Letters Patent.

Patented Feb. '28, .1922.

Application filed August 16,1920? Serial no. 404,003.

To all whom it may concern Be it known that 1, ANDREW G. lVAss, a

citizen of the United States, residing at Min-' neapolis, in the countyof Hennepin and State of Minnesota, have invented certain new and usefulImprovements in Combined Lock Bolts and Joint-Packing Strips for FrenchDoors; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as w ll enable others skilledin the art to which 1t appertains to make and use the same.

My invention has for its object to provide an exceedingly simple andhighly efiiclent combined look bolt and joint packing strip for Frenchdoors; and, to such ends, generally stated, it consists of the noveldevlces and combinations of devices hereinafter described and defined inthe claims.

It is a well known fact that it is difficult to make tight joint stripswhich will entlrely exclude both wind and water without much complexity.

The preferred form of this improved device is illustrated in theaccompanying drawings, wherein like characters indicate like partsthroughout the several views.

Referring to the drawings,

Fig. 1 is a front elevation of my improved combined lock bolt and jointstrip mounted on one of a pair of French doors;

Fig. 2 is a vertical section taken on the line 22 of Fig. 1; with someparts broken away;

Fig. 3 is a horizontal section taken on the line 3-3 of Fig. 1, lookingupwards; and

Fig. 4 is a vertical section taken on the line 4-4 of Fig. 1.-

The numeral 5 indicates an ordinary French door on which my invention ismounted and 5 an ordinary door casing on which said door is hinged. Alock bolt 6, having an operating handle 6, is held in operative positionby. outside guides 7 and. 7 fastened to the free end of said door,providing for free vertical movement of the bolt. The numeral 8represents a joint packing strip or blade connected to said lock bolt 6by means of a common sliding bar 9 to which both are secured by screwbolts 10.

which engage in the threaded holes 11 of the bar. The said blade orplate 8, it will be noted is wider at its end portion where it isattached to the bar 9 and tapers therefrom to a considerably smallerWidth adjacent the first guiding member 17 and from this point to theother side of the door is of uniform width. A recess 12 in the bottom ofsaid door is provided in which said sliding parts are mounted.

A threshold plate 13, having an inclined packing shoulder 14 forengagement with said blade 8 and a bolt socket 15, is fastened to thethreshold 16.

v The packing blade 8 is guided by a series of U-shaped guide plates 17inserted into the bottom of the door, secured thereto, and by flat endguide plates 18 fixed on the oppos te door edges. A long guide strip 19,secured to the bottom of the door, co-operates with the guides 17 and18.

Said lock bolt has a beveled nose 20 to make it easily engageable in itsbolt socket. Likewise said blade 8 has rounded edges 21.

With the device described, the operation is probably obvlous. When in aninoperative position, the friction of the several guide plates and thebolt guides is suflicient to hold said blade and bolt from dropping. Tooperate, the bolt 6 is thrust down into its locking socket carrying withit the blade 8 and camming the same against the inclined packlngshoulder of the threshold, making said threshold absolutely wind-tight.The U-shaped guide plates 17, best seen in Fig. 1, guide said blade 8and also provide a stop for said blade, when the lock is raised, by anupward thrust. The end guide plates 18 and the elongated guide strip 19facilitate materially in this guiding action. The recess 12, cut out ofthe bottom of said door 5, allows said sliding parts to be mountedtherein and provides the necessary clearance for their manipulation.

My invention maybe, of course, applied to casement windows, ordinarydoors, or any swlnging sash and may be used vertically or horizontallywith equal efiiciency and simpliclty wherever a wind-tight strip isneeded in combination with a lock bolt.

What I claim is V 1. The combination with a door and threshold plate, ofa lock bolt and joint packmg blade mounted on the door and rigidlyconnected for common movements to simulvtaneously project said bolt andplate into operative positions, said blade having one end widened andsaid blade extending across the width of the door the widened end beingsecured to the bolt to enable the entire width ture, a sliding boltsecured to the one side of the door adjacent its front lower edge, a barattached to one side of said bolt adjacent the bottom thereof anddisposed in a slot in said door, a blade rigidly secured to said .barand also disposed in a'slot in said 10 door and extending from said baracross the Width of said door and adapted to be moved With'said bolt, athreshold block having a hole therein for receiving said bolt, and aninclined edge against which the said blade is 15 adapted to Wedge;

In testimony whereof I afiix my si nature. ANDREW G. ASS.
